Why does it say in Is. 53:5 we are healed and in 1 Peter 2:24 We were healed.

In Is 53:5 it is a now healing. In the old testament they had to do sacrifices regularly. It could never put healing in the past or behind them. Because Jesus had not yet come. BUT…

After Jesus came now we can say:

We are healed. Past, it is done & always will be that way. Today can’t change what Jesus did. No more sacrifice for it. “IT IS FINISHED”. (We must receive it)

Malachi 3:6 “I am the Lord, I change not”

What He did, He will do again. Rom 2:11 For there is no respect of persons with God.
